This'invention relatesto a coin-controlled operating mechanlsm for vending machines I and the like, as described in the present specification and illustrated in the accompanying ,;drawings which'form partof the same.

The invention consists essentially of the novel. features pointed out broadly and specifically inthe claims for novelty "following a description containing an explanation in dc to." tail' of an acceptable form of the invention.

' -The objects of the invention are to con, struct a' coin-controlledoperatingdevice of simple and dependable construction, positive of; operation, and one especially adapted for loivending machines. j A A v *In the drawings, Figurel is an outside plan view of the'base plate. I

Li ke numerals of" reference indicate'corresponding parts in the various figures j i Referring to the drawings, is'a circular 3o; disc or base platehavin the central opening 36 surrounded by the raised bosses 37 and38 which project out'from the outer and nner faces respectively, of said disc; 39 are raised peripheral portionsof equal width formed leave the gaps 41 and 42.

bearing ,44 sized to fit androtate' in the hole 36 405of the base plate 35, and formed wlth the raised annular portion 45 projecting out fronr the inner face thereof;,the portion- 45 ,is depressed in .at 46 toslightly" more than the thickness of the prescribed coin or coins, I 45 fdesignated by-the numeral 74. The depressionv 46 formsfwith'theibase plate when the coin-driving plate is assembled to or upon saidbase plate, the coin-chamber vor magazine.. The raised annularv portion 45 is made plate and formed to be fastened to the vendtween the raised boss 38 and the peripheral portions 39, while the inner face of said'disc- 43 bears or slides upon the boss 38 and the portions 39; The disc 43 is rigidly mounted upon a shaft 49 as with a set screw 49A threaded through the boss 51 and engaging said shaft. The shaft is introduced through the opening 36 of the base plate and the disc 43 retained in its assembled position upon said base plate as with the collar 52 held rigidly upon the bearing 44 by means of the set screw 53. The shaft'49 extends beyond the end of said bearing 44 to receive a suitable gear 54, the gear being rigidly secured upon the shaft in any suitable manner, as with a pin 55 passed through said gear and inserted into a hole 55A made in said bearing 44,,as shown'inFigure'6."

56 are metal straps secured' to the base ing machine. The shaft 49. is made long enough to extend through the wall of the vending machine and'to receive the crank 57 The base plate is therefore fixed while the {disc 43 can be rotated upon said base plate by a turning the crank 57. '60 is a short lever rigidly carried by a spindle 61 rotating in brackets 62 carried by the outer face of the base plate 35; 59 is a pin sliding in said base plate andhaving the top end'slotted in asat 65 to receive the end of the lever'60; 64 is a small'pin passed through the pin 59 above the lever 60 and projecting v out on each side thereof; 63 are tensioned spaced to springssecured at the top to. the pin 64 and 55 secured at the bottom tothe base plate, so

that the actionof the springs is to swing or tend to swing the lever 60 downwardly. The spindle 61 rigidly carries the fingers66 which pass through slots 67 made throu h the base plate 35. The downward travel of the pin 59 under the action of the tensioned springs 63 is limited or checked by the engagement of the fingers 66 with the end of the slots 67, as best shown in Figure 5. V v The fingers 66 are made long enough to project beyond the inner faceof the basev plate, or' in other words, to project into the groove 48, so that as the coins. are forced or slid within said groove by the rotation of,

the disc 43, their engagement with the fingers will tilt these, tilt the lever 60, and raise the pin 59 until its lower end face 68 lies between the inner and outer faces of'said base plate; The peripheral edge of the disc 43 is depressed in at 69 to provide the shoulders 70' and 71 which limit or check the rotation of the disc relative to the base plate by their engagement with; the pin 59. Therefore, unless the prescribednumber Off coins are insertedinto thecoin chamber'to engage the ends ofthe,fingers,66Mwhe1nthe] disc is rotated in the direction of the arrow, the pin 59 will lie in thepath-ofthe-shoulder 70 and thus checkthe rotationlof said disc. If -onthe other hand, the prescribed number of 1 coins are inserted :into the coin. chamber throughthe slot orgap 41, the coins -will engagethe fingers and cause-the pin 59 tobe zoi'li-ft'ed, the disc being now free to rotate;

Therbase plate is so secured in the vending machine that the coinslot or gap 4l}prefer-- ably" lies slightly to one-side ofka--verticallineidrawn through the centre of said base 25.;zplate', or in about the position shown in Fig-f V u're 1.'-' The shoulder 71in the disc 43 must be soydisposed relative to the coin chamber 7 that the gap 41 will open into 'or'communicate with the coin chamber when the shoulder-71 =engages the pin 59'; The shoulder 72 must be so disposed relative to the shoulder 70 andkth'e distance between the;pi-n-- 59 and the fingers 66 be such that theishoulder -70 will engage the pin 59 before the shoulder'72 engagesthe fingers, OI" 'lI1 other words, the shoulder 7 O'must engage the in 59"before I the shoulder 72 reaches the position of'tthe fingers 166'; but the arcual'distan'ce between thefshoulders 70 and 71 must be more' -than 40am clearance left between thecoinsand "the shoulder 72, so that the engagement of the" coins with the fingers willcause thepin 59 to; move. out of the wayofthe shoulder 70 when 'the disc 43"is rotated.
